FSD1 — Solanum lycopersicum

Summary

SOLYC06G048410.4, also known as FSD1, encodes a manganese/iron superoxide dismutase (Mn/Fe SOD) family protein with superoxide dismutase activity, as well as RNA endonuclease, siRNA and miRNA binding, and protein kinase activities. In tomato, this gene is associated with lycopene breakdown, oxalate metabolism, chromate transport, and the regulation of glutathione anabolism. It has been linked to numerous agronomic traits including fruit volume, leaf moisture and nitrogen content, seedling height, germination ratio, stem thickness, root weight and volume, and cell membrane stability. The gene is also associated with oxidative stress tolerance, salt stress tolerance, copper deficiency response, and chloroplast biogenesis. Studies of related genes in other species link the family to superoxide detoxification, salt stress response, and miRNA activity.
